This may be a slight tangent, but while early switchable GPUs had both
GPUs connected to the display through a multiplexer, on current setups
only the integrated/weak/low-power GPU is actually connected to the
display, and the other GPU is actually headless. The GPU connected to
the display is then responsible for getting the contents of the other
GPU onto the screen. I'm not sure how accurately that topology is
reflected by the relevant MacOS APIs.
